In this chapter, we report an overview of the national estimates for the use of medicines in Malaysia for year 2007. The most commonly used
medicines by therapeutic groups and by specific drugs are tabulated below. More detailed statistics and analysis of medicines utilised are given
in other chapters in this report.
As in previous years, the National Medicines Use Survey (NMUS) 2007 was limited to “prescription” medicines only; it excluded Over-the-Counter
(OTC) medicines and Traditional Medicines. Also, utilisation data presented in this chapter included only drugs that have Defined Daily Doses
(DDDs) in the World Health Organisation (WHO) Anatomical Therapeutic Chemical (ATC) classification system,1 and the estimates are expressed as
number of DDDs per 1000 population per day. Hence the discussions in relation to ranking and comparison of usage in this chapter do not include
drugs which do not have WHO assigned DDD and are not prescription medicines.
However, estimates for utilisation of some medicines which do not have WHO assigned DDDs are presented, in terms of weight of active
ingredient/1000 population per day (Antineoplastic drugs) or weight or volume of drug preparations per 1000 population per day (Dermatologicals,
Ophthalmologicals and Otologicals), in other chapters where the utilisation of these drugs within their respective groups are discussed.
Among the therapeutic groups, drugs used in diabetes (ATC code A10) ranked highest in terms of utilisation in Malaysia for the year 2007 (Table
1.1) as was in 2006 (Table 1.2). An estimate of 3.97% of the Malaysian population was on drugs from this therapeutic group. This correlates well
with the national diabetes prevalence of 4.0% in the general population reported in the Third National Health and Morbidity Survey 2006 (NHMS
III).2
The therapeutic groups used for cardiovascular disorders, namely agents acting on the renin-angiotensin system (C09) consumed by 2.67% of
the population, beta blocking agents (C07) consumed by 2.62% of the population, calcium channel blockers (C08) consumed by 2.31% of the
population, diuretics (C03) consumed by 1.40% of the population and lipid-modifying agents (C10) consumed by 1.39% of the population, were
ranked 2nd, 3rd,4th, 5th and 6th respectively (Table 1.1).
Drugs for obstructive airway diseases constituted the next highest ranking group of drugs. However, there was not much difference in total
utilisation between 2007 (12.59 DDD/1000 population/day) and 2006 (11.73 DDD/1000 population/day).
As far as individual drugs were concerned, ranks 1 to 11 by utilisation for 2007 went to drugs for diabetes and cardiovascular disorders (Table
1.3), again reflecting the pattern for prevalence of chronic diseases reported by NHMS III where hypertension, diabetes and heart diseases ranked
1st, 2nd and 4th among the top chronic illnesses. Overall, there was not much difference in ranking for the top 5 drugs by utilisation when compared
to 2006.
Metformin (consumed by 1.43% of the population), followed by glibenclamide (consumed by 1.28% of the population), were the top 2 antidiabetic
drugs as well as the top 2 among all drugs utilised. Metformin was recommended as first-line therapy in the treatment of Type 2 diabetes mellitus
according to the Malaysian Clinical Practice Guidelines (CPG) at that time.3 This may reflect some improvement in terms of adherence to the
guidelines compared to 2006 where usage of glibenclamide superseded metformin.
It is interesting to note that usage of amlodipine had gone up from rank 9th in 2006 to rank 6th in 2007, with almost 70% increase in utilisation.
Usage in the public sector in 2007 was double that of 2006. Perindopril had also climbed up the chart from being only at rank 11th in 2006 to
rank 7th in 2007, again with almost 70% increase in usage. The increase in utilisation of amlodipine and perindopril may possibly be attributed to
the findings of the Anglo Scandinavian Cardiovascular Outcome Trial (ASCOT), which was published in 2005.4 Also, generic versions of amlodipine
became available following expiration of its patent.

Asthma was the 3rd highest ranking chronic disease reported in NHMS III. It is therefore not surprising that inhaled salbutamol (R03A) occupied
12th position in the 2007 utilisation ranking for individual drugs, an improvement from its 13th position in 2006, with approximately 30% increase
in usage. Usage of budesonide, an inhalation steroid, however, dropped from rank 25th in 2006 (1.787 DDD/1000 population/day) to rank 38th
(1.1984 DDD/1000 population/day) in 2007. Although detail statistics in other parts of this report showed general decrease in use of single-
ingredient inhaled glucocorticoids, there was an overall increase in use of inhaled combination glucocorticoids with long-acting beta agonists.
It is also interesting to note the improvement in rankings of oral contraceptives. The combination levonorgestrel and oestrogen which ranked 31st
in 2006 moved up to 21st in 2007, whilst the desogestrel and oestrogen combination, a third generation oral contraceptive, emerged as a new
member in the top 40 drugs by utilisation list at rank 39th (2007), moving up from 49th in the previous year. In terms of utilisation, there were overall
increase of 1.12 DDD/1000 population/day and 0.28 DDD/1000 population/day, respectively, for the 2 combination oral contraceptives (equivalent
to an increase of 75% and 30%, respectively).
Comparing the Malaysian drug utilisation pattern with that of Australia5 and Norway6, whilst cardiovascular drugs dominated the top 10 drugs by
utilisation in all 3 countries, ranking for individual drugs for Malaysia differed somewhat from that of Australia and Norway as shown in Table 1.6.
The most significant differences are the presence of nervous system drugs in the top 10 drugs for Australia (sertraline (N06AB06) ranked 7th) and
Norway (zopiclone, (N05CF01) ranked 4th); both these drugs are not even in the top 40 drugs in Malaysian ranking. Metformin, the most highly
utilised drug in Malaysia did not feature among the top 10 drugs for both Australia and Norway although the consumptions were comparable -
14.28, 15.65, 11.98/1000 population/day, respectively, for Malaysia, Australia and Norway; in fact, neither did any of the other antidiabetic drugs
make it to the top 10 list for Australia and Norway. Diabetes prevalence in Australia was 3.6% (2005-2006)7 and Norway 4.7% (2007).8 Instead,
the lipid-modifying drugs, atorvastatin and simvastatin topped the Australian and Norwegian list, respectively.
The National Medicines Use Survey (NMUS), amongst other objectives, is designed to support the implementation of the National Medicines Policy
which promotes equitable access to essential medicines. Hence, it is pertinent to note that 10 out of the top 40 drugs used in 2007 are not in
the Malaysian National Essential Drugs List (NEDL) 2008.9 These included amlodipine, an antihypertensive drug (rank 6th), loratadine, a commonly
used non-sedative antihistamine (rank 24th), cetirizine (another antihistamine) which saw a 51% increase in usage and improved ranking from 32nd
(2006) to 25th (2007), and simvastatin (a lipid-modifying drug) which has been consistently in the top 40 drugs used (rank 17th in 2006 and 16th
in 2007). Based on the utilisation patterns established by NMUS, there is an apparent ‘mismatch’ between what is most used and what is listed
in the NEDL in some therapeutic areas. Whilst the NEDL serves only as a guide to drugs which should be available in the country, there is need to
regularly update the medicines selections to reflect new therapeutic options and changing therapeutic needs.
The NMUS showed that the drug utilisation patterns in Malaysia concurred with prevalence of chronic diseases reported in NHMS III. It also showed
that for both 2006 and 2007, the overall drug utilisation in the public sector was twice that of the private sector for the top 30 therapeutic groups.
Twenty of the thirty most utilised classes of drugs were for chronic diseases, and public sector utilisation exceeded that of private sector, indicating
an imbalance in burden borne in the management of these diseases. This also concurred with the NHMS III which found that government health
centres were the most frequently visited by respondents with chronic diseases followed by private clinics.
However, the pattern was reversed for drugs used for short term symptomatic relief such as antihistamines, anti-inflammatory and antirheumatic
drugs, nasal preparations, drugs for gastrointestinal disorders and corticosteroids, where private sector utilisation was higher. Interestingly, the
NHMS III found that among those who used ambulatory services for recent illnesses, 62.1% went to private clinics whilst 37.9% used government
clinics.10
In conclusion, the overall utilisation pattern of medicines in the country for 2006-2007 appeared to be in accordance with the general healthcare
needs.
